The metal expansion joint is used as a protective measure due to the large temperature change when connecting the expansion pipe or corrugated pipe. The metal expansion joint is used to connect the pump, valve, pipeline and other equipment with the pipeline, and it is connected by full bolts to make it a whole, with a certain displacement, which is convenient for installation. It can withstand the axial pressure of the pipeline. In this way, it can be adjusted according to the on-site installation size during installation and maintenance, which can not only improve the work efficiency, but also protect the pump, valves and other pipeline equipment.
Working Principle
The pipeline has large expansion, high temperature and strong pressure area. In the building water supply and drainage engineering, the foundation concrete pouring or embedded pipes. In the process of these engineering pipes being subjected to the building foundation settlement, equipment resonance, geological changes, and changes in the pipeline medium, the pipeline distribution positions begin to be stressed, deformed, distorted and damaged. The embedded pipes even break, which brings great inconvenience to the construction unit. In order to overcome these difficulties and ensure the safe operation of the pipeline, expansion joints Metal expansion joint: it can expand and contract axially within a certain range to overcome various angle displacement, misalignment, expansion and expansion of the pipeline. The pipe can expand and contract freely in the expansion joint. Once the expansion exceeds *, it will limit the position itself. So as to ensure the safe operation of the pipeline.
